• Can not override safari's default search in safari app extension?

  I am developing safari app extension in xcode using swift language to take over default search to my site.

  I have updated info.plist file to inject script.js file in every page as using SFSafariContentScript.

  I have tried using below code in script.js file to add event to default search box, but its not working(It was working in legacy Safari extension).

  safari.application.addEventListener("beforeSearch", getSearchText, true);
  function getSearchText(e) {
      alert("hi, this is from search box");
  }
  

  Does safari app extension have support to adding events to search bar ? Any help on this is appreciated.

  Thanks in Advance!

• Pam authentication not being applied for non root user in ubuntu

  I created .so file which print "welcome to .." to shows a welcome message when user connect with other user using openssh.

  I also gave the reference into "/etc/pam.d/sshd" file and "/etc/pam.d/common-auth" same as google authenticator.

  When I begin any command with "sudo" word my "welcome to .." message shows.

  So now i want that welcome message print when any user(non root = does not start command with sudo) which work under the admin when try to entering a password it will print welcome message.

  Please give response as early as possible. Thank you.
• Length of the decryption(RSA) string is changing

  I have a String which is encrypted with RSA algorithm, When i was trying to decrypt it's working fine.The decryption output will be in byte[].

  My question is when i trying to convert the byte[] to a new String(decrypted String) it's getting different length .

  If i try with a random string the length is remains same.But if i decrypt the generated aesKey(AES) the length of the byte[] is changing while conversion of new String(decrypted String).

  Why i am getting different length incase of aesKey decryption??? Is there any difference between "random string" and "generated aeskey"

  String == "t8xypyI6gKlKTkt4Qec7FCor4EpukZXqYQcIDm6YvbtRB9+YBrX0CqyoHOHN91T8RBQS/JD2osbf4ao9Y"SgNbzhfDa2NpJKMEIBWH4TNlF4Ngb8yWdSm3hz3l8FdeFUIy3pyCxkLjU8n4VAxsmgoIQbgd7DJuPiSMZBA9/IVlcCfo/tZjMtSkezITtoT5aVvLxLaTsp08UREdalvXxb5USKi3cAEdqR9TmLJxB004IMv5Eiuvdmcc3fJzO6mnwiHPuGKArd9LjjiqbPQ75uc8NDOFrvleLc5KwSuThS5Xx7tR1qfoX6qefh6SD7FRk5UzyCEnv+eD+mCQ588Jam1A==";

  ****The above string is encrypted form of the aesKey(generated by KeyGenerator)

  If i decrypt this string by using RSA----

  private String decrypt(String text, Key privatekey) throws NoSuchAlgorithmException, NoSuchPaddingException, InvalidKeyException, IllegalBlockSizeException, BadPaddingException {
      byte[] dectyptedText = null;
  
      Cipher cipher = Cipher.getInstance("RSA/ECB/OAEPPadding");
      cipher.init(Cipher.DECRYPT_MODE, privatekey);
      dectyptedText = cipher.doFinal(Base64.getDecoder().decode(text));
      System.out.println(dectyptedText.length);                  //32
      System.out.println(new String(dectyptedText).length());    //30
      System.out.println(new String(dectyptedText).getBytes().length); //60
      return new String(dectyptedText);
  
  }
  

  above, The length is changing in byte string conversions.

  Suppose if i encrypt and decrypt with a normal string the lengths are not changing????why????

• Sending data between computers on different networks C#

  I was interested on making a basic vpn system so I went on the lookout for some C# code that would allow me to share data between computers on different networks. I thought i had it but I can't get it to work across other networks:

  ShowCapital sh;
      private void Form1_Load(object sender, EventArgs e)
      {
          TcpClientChannel channel = new TcpClientChannel();
  
          ChannelServices.RegisterChannel(channel, false);
  
          RemotingConfiguration.RegisterWellKnownClientType(
              typeof(ShowCapital), "tcp://203.184.17.120:1234    /Showcapital");
          sh = new ShowCapital();
  
  
      }
  

  Just to clarify: this example script exchanges country data, that's why the confusing variable names.

  Basically i don't know what to fill in after "tcp://" in order to get data to transfer over different networks. Only local IP address seem to work.

  (By the way, i'm kind of ish new to coding) Just in case it wasn't clear, this is on winforms.

  Thanks to anyone who can help!
• Register time, date and e-mailadress of download in a database?

  Hello good friends of the internet.

  I have a client that wants to share PDFs on their wordpress website and keep track of who have dowloaded a specific quotation. The guy who initiated the request have now quit but they still want it and asked if I could possibly help them out. I promised I'll ask around atleast. :)

  So, the situation:

  As of today they send out a link www.domain.com/quotation/project-name and their clients dowload a PDF from there. Simple enough.

  But instead they want to manually send a link with their clients specific e-mail adress www.domain.com/quotation/?email=name@domain.com, once clicked they want you to end up on a simple landing page with a dowload button for the specific quotation, and if you download the PDF they want to register time, date and e-mailadress in a simple database. The PDFs are uploaded trough FPT on their end btw.

  Any idea how one should approach this, or possibly point me in the right direction?

  Cheers!
• How to create data sharing and chat app across network without any servers?

  I want to create a mobile application that will not store any data in db or use any server for data or message transfer. Some messages or file will be saved in mobile storage but thats not important.

  I want to make the mobile application connected through IP without setting any server, not even p2p server.

  Any help in this regard would be appreciated. I also wanna know if this is practical or achievable, if not what are the blockers and alternatives?
